如何在DataGrid中获取电话号码格式 [英] How to get phone number format in DataGrid

问题描述

大家好。

在我的数据网格中，我尝试使用stringformat格式化电话号码：

In my datagrid I try to use stringformat to format phone number:

<DataGridTextColumn Header="Phone" Binding="{Binding Path=Phone, StringFormat={}{0:(###) ###-####}}" Width="100" />

但无法获得结果。哪里出错？

But cannot get result. Where is mistake?

谢谢。

您好zleug，

Hi zleug,

如果您的电话号码属性是字符串类型，我认为StringFormat不起作用，您可以尝试使用IvalueConverter。

If your Phone number property is of type string, I think the StringFormat is not working, you can try to use IvalueConverter.

 <Window.Resources>
        <converter:PhoneConverter x:Key="phoneconverter" />
    </Window.Resources>
    <Grid>
        <DataGrid AutoGenerateColumns="False" ItemsSource="{Binding phones}">
            <DataGrid.Columns>
                <DataGridTextColumn
                    Width="200"
                    Binding="{Binding phonen, Converter={StaticResource phoneconverter}}"
                    Header="Phone number" />
            </DataGrid.Columns>
        </DataGrid>
    </Grid>

 public partial class Window26 : Window
    {
        public ObservableCollection<PhoneModel> phones { get; set; }
        public Window26()
        {
            InitializeComponent();
            phones = new ObservableCollection<PhoneModel>()
            {
                new PhoneModel(){phonen="1231231234"},
                new PhoneModel(){phonen="1231231234"}
            };
            this.DataContext = this;
        }
    }

    public class PhoneModel
    {
        public string phonen { get; set; }
    }

 class PhoneConverter:IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            double a = System.Convert.ToInt64(value);
            return a.ToString("(###) ###-####");
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

最好的问候，
